“You’re going to be sick of it all one day, and when you are, I’m here to talk or listen.”

“Oh honestly, Granger,” there was that signature smirk, “how long did it take you to come up with that little speech? And you practiced it at least fifty times, no doubt. When are you going to learn that sometimes a little improvisation is necessary?”
